A jewelry expert shares an estimated value for the ‘obscure’ piece of jewelry and tells PEOPLE what makes the customized gift is so special

North West got her mom Kim Kardashian a 𝐛𝐢𝐫𝐭𝐡day gift befitting of a hypebeast.

The mogul, who turned 44 on Monday, Oct. 21, took to Instagram Stories to share a video of the diamond necklace her 11-year-old daughter gifted her.

The sparkling piece features a diamond tennis chain and gold name plate with an engraving that reads “Skibidi Toilet” (a reference to the viral computer graphic web series). On the back, the plate is engraved with “Love, North” and includes the date.

According to jewelry expert, the ‘obscure’ custom piece could be worth up to $20,000. Olivia Landau, CEO of jewelry brand The Clear Cut, estimates that each diamond on the necklace contains roughly .08 to .10 carats.

“It also appears to be a solid plate engraved ‘Skibidi Toilet,'” Landau tells PEOPLE. “The estimated value of this necklace could be around $15-20k.”

Detroit-based celebrity jeweler George Khalife (known professionally as George the Jeweler) tells PEOPLE that “based off her hand against the necklace, it looks like it would be approximately 10 carats.”

Landau also shares that the piece combines two major trends right now — tennis necklaces and customizable name plates.

“People love being able to create added sentiment with their jewelry pieces, especially when gifting,” she says.

Khalife, who has worked with the Kardashians before, adds that this piece is special because it represents the special relationship between Kim and North.

“The phrase is a viral TikTok trend and represents the inside jokes made between been her and daughter as we have all see the fun TikToks they do together,” he says. “It is a one-of-a-kind necklace that captures this time in her life and makes for a memorable and funny 44th 𝐛𝐢𝐫𝐭𝐡day gift.”

It’s not exactly surprising that North, who is already making her mark as a style icon, would pick out such a trendy piece for her mom.

North, who is the eldest 𝘤𝘩𝘪𝘭𝘥 of Kim and ex-husband Kanye West, recently spoke with Kim about for Interview Magazine, where the pair discussed North’s style influences.

In a clip of their chat posted by Kim on her Instagram Stories, she asked North, “What’s your favorite style right now?”

“I like streetwear and ’90s. Tyler, the Creator; my dad; me!” North replied.

Kim and Kanye, who divorced in November 2022, also share three other 𝘤𝘩𝘪𝘭𝘥ren: son Saint, 8, daughter Chicago, 6, and son Psalm, 5.

During the interview, North also revealed that she plans to start her own clothing line, following in her parents’ footsteps.

“Well, I am starting my own clothing line,” she shared. When Kim asked, “And what are you going to call it?” North said: “North West.”
